Scientists have invented incredibly thin, flexible photovoltaic cells that are so lightweight, they can rest on top of soap bubbles without breaking them. Cells this thin and light could eventually be placed almost anywhere, from smart clothing to helium balloons.
“It could be so light that you don’t even know it’s there, on your shirt or on your notebook,” said one of the researchers, Vladimir Bulović from MIT. “These cells could simply be an add-on to existing structures.”
It’s that versatility that makes the experiment so exciting - even if it’s still only a proof-of-concept at this stage. Key to the creation of the new cell is the way the researchers have combined making the solar cell itself, the substrate that supports it, and its protective coating, all in one process.
Awesome.
